character described which is adapted to be disposed within a windowopening and which "in;-

.cludes means whereby it 'may be readily positioned within such anopening even thoug h' 'the opening may vary somewhat from the requireddimension. The fixed window frames that surfround window openingsvarysomewhat in'dimension from their intended size. My improved frameassembly, which is adapted to be disposed within the fixed frame aboutthe opening," is provided with adjustable means which is readilyoperable to fit my improved frame assembly 'to the frame of the opening.7

Another object is the provision of an improved sash and frainelassemblyQforme'd'of s tfmetal and wherein the upright jamb portions of'jt'heframe assembly are relatively flexible with sup} porting strips adaptedto be adjustably' positioned between the 'jamb portions of the frameassembly and the fixed jamb members of the stationary window frame aboutthe opening.

A meritorious feature of'my invention is that the window frame assembly,which includes rip;-

right opposed side frame members having jamb portions providedwithcomplementary sash guide channels within which asliding sash isdisposed, also includes a pair of wedge strips vexte din'g along theback o'f thejamblp'ortions o f'ft e side frame members'andwhichwedgestrips 'aije'ladjustable laterally with respectto the iambiportions ofthe side frame members to. rigidlyfsuppert t e windowframe'assemblylwithin the window Opening and to an the gap'b etw eh theIjamld partions of the siaeria'msme'mbersand thejamb'elements of thestationary window frame. These wedge strips may also be adjustablypositioned so as to accommodate the window frame assembly to windowopenings varying slightly in size. Means is provided to move the Wedgestrips laterally to fit the frame assembly to the opening.

Other objects, advantages and meritorious features will more fullyappear from the following description, claims and accompanying drawingwherein:

1 is a front elevation of a fragment of a building wall exhibiting a'window opening" in which a frame assembly embodying my invention isdisposed. J Fig. 2' is a horizontal sectional view taken on the line 2 2of Fig. l, with the wedge strip backed off from the outer cornerof'theblind stop.

Fig.3 is a horizontal'secti'onal viewtaken on theline 3 3 of Fig. 1,showing the'wedg'e' strip in contact" and abutting the 'outercorner' ofthe blindstop.

In the drawing there is shown a building window opening surrounded by astationary frame provided with a sill t0 at the bottbinfa header 'jltz'a'nd outer casing members I14. This'istationairy frame also includesjanib element's each'o'f which includes a jamb member l6 and afioute'rstop l8 secured thereto. Theouter or b'lindst'op I 8"'forms the outerwall of the guide channel for .an upper vertically slidable sash mountedwithin the stationary window frame and not sh in the drawing because itforms no part of jsi re' o The co ven o a stat o r wi ido'w frame thatsurrounds the windowiopening is normally fitted with an upperandalower'vertically slidablewindow sash 'which"con stitute no part f thisparticular invention and these have been omittedfromthedrawings.' T ""Myinvention relates tothe window frame and .SaSh assembly, which is hereshown as a combination storm window and screen sash assembly, whichisadapted to be mountedwithin the'win- .T s i rame .t u o nd th ndow o ngfih ra i w dewfi'e f n sa assem l isjshown and moreparticularlydejscribed in my application, Serial No. 36,766,1i1dofle'v'en date herewith, now abandoned.

' jsuch a frarneand sash assembly comprises as of trjateda frameformedof sheet' m'eta'l, for e ample aluminum, and 'includingfuprightside frame portions, a h'eader'portion 2 0 and a-"sill portion 22. Eachside frame portion includes a iam rar 2.4 and.a bas n i r l? jes l an hem -pan 2 is h d to ,A fine tlireelsashjgdide channels withlnlwhich"outer storm sash} an inner storm window sash, and a screen sash aremounted for slidable movement.

In Fig. 3 the outer sash is indicated by the numeral 28. The other sashelements are not shown in place. Tension springs 30 are mounted withincertain guide channels as shown in the drawing, (Fig. 2) the characterand purpose of which tension springs are described in my applicationabove identified. Generally, they serve to exert a pressure against thesliding sash to hold 3 7 them against rattle and they function withinthe deep guide channels to yield to facilitate the removal of the sash.

The casing parts 26 of the side frame members may be secured by screws32 or the like to the casings I that surround the window opening. Theheader portion and the sill portion 22 of the frame assembly may besimilarly fastened in place by screws.

A wedge strip 34 extends lengthwise along the back of the jamb portionof each side frame member as shown in Figs. 2 and 3. This wedge striphas a bevelled face 35 which is adjustable to seat against the outercorner of the blind stop l8 as shown particularly in Figs. 2 and 3 toposition and properly support the frame assembly within the windowopening. A pin 36 is rotatably mounted within the casing part 26 but isheld against axial movement by a collar 38. Specifically this collar isin the form of a ring received about a reduced diameter portion of thepin as shown in Fig. 2, and serving as a collar thereon. The pin has ascrew head whereby it may be rotated. The shank of the pin is threadedas shown and has threaded engagement with an aperture 40 in the wedgestrip 34 whereby the wedge strip may be advanced or retracted laterallyover the back of the jamb part 24 of the frame assembly as illustratedin Fig. 3.

It will be seen that the wedge strips 34 may be moved laterally over theback of the side frame members and wedged between such side framemembers and the blind stops I8 to form a rigid supporting base for theside frame members. Inasmuch as these side frame members are formed ofrelatively thin sheet metal their jamb portions 24 are somewhat flimsyand these wedge strips afford a solid backing for them. The wedge stripsalso fill the gap between the side frame members and the blind stops 18as shown in Figs. 2 and 3. The wedge strips also, because oftheirpermitted adjustability, facilitate the fitting of my improvedframe assembly within openings which may vary somewhat in size.
